POWER INPUT CORD  — Heavy -duty cord supplied to the requirements of your local. In USA: Connect only to 110-120 
VAC, 60 Hz.  Always use grounded outlet (3 terminal) to avoid operating problems and to increase safety margin.  
 
FUSE — Use fast-blo 2 Amp for 120 VAC or 1 Amp for 220-240 VAC models. Always replace with the same type and 
size fuse.  
 
SPEAKERS — Connect only to speaker supplied.  Note: Use of external speaker may void warranty. 
 
FOOTSWITCH — Switches overdrive on and off.  
 
EFFECTS SEND — Proper send level for most effects devices. Connects to the "in" or "guitar” jack of your effects. Can 
also be used as a D.I. (Direct Input) to a mixing console or recorder.  
 
EFFECTS RECEIVE — Unity buffered input from effects devices. Connects to the “out” or "amp" jack of your effects. 
Can also be used as a direct Power Amp section input.   
 
NOTE: A common problem many encounter while using effects devices is "ground loops". A ground loop is often caused 
when an effects device, mixing board or tape recorder equipped with a 3-prong AC cord are connected together with au-
dio cables. The electrical difference between the AC ground (at the AC plug) and the signal ground (audio cords) is am-
plified. This may result in increased hum levels and in some cases high-pitched squeals or oscillation at high gain set-
tings of the amp. The solution is often to use the same outlet strip for all equipment rather than plugging into various 
separate outlets. In extreme cases it may be necessary to isolate the AC grounds. If this is attempted, consult a qualified 
technician to insure safety. Tube Works cannot recommend the disabling of any 3rd prong grounding plugs.
